There’s only one week left until Microsoft stops all support for Windows XP’s Service Pack 2.

The company website reads, “Important notice for users of Windows XP with Service Pack 2 (SP2): The support for your product will end July 13th, 2010. To ensure that you will receive all important security updates for Windows after that date you need to upgrade to Windows XP with Service Pack 3 (SP3) or later versions such as Windows 7.”

Notice the subtle hint about upgrading to Windows 7 there.

This means that if you’re running Service Pack 2 and don’t upgrade to Service Pack 3, “you won't get security updates for Windows”.

Support for Windows Vista without any service packs ended on April 13th, 2010.

Windows XP is still the most popular OS out there, though Windows 7 has already become Microsoft's fastest-selling OS to date with over 150 million licenses sold since launch.
